Multiplexing of imperceptible temperature sensor arrays for on-skin applications — •Tetiana Voitsekhivska, Jürgen Fassbender, and Denys Makarov — Helmholtz-Zentrum-Dresden-Rossendorf e.V., Dresden, Germany

Beside the direct temperature measurement resembling the standard health indicator, the access to the body core temperature and its temporal variations provides the information, which is absolutely crucial to assess the psycho-physiological conditions of the patient, e.g. level of stress. To measure spatial and temporal temperature gradients, multiple temperature sensors have to be attached and processed on the human body surface [1, 2].

Here, we introduce a thermal characterization technology for real - time monitoring the human body temperature using arrays of highly compliant on-skin temperature sensors, realized on 6-micrometer-thick polymeric foils, which are haptically not perceived when worn on the skin. Beside the realization of the arrays of imperceptible temperature sensors, we put strong emphasis on the integration of a multiplexing unit on flexible foils in order to achieve measurements with mapping capabilities.
